Here is my correspondance with BMW pertaining to this subject.
Dear Mr. Vipond,
Thank you for contacting BMW Motorrad USA regarding your 2006 BMW K 1200 LT. We appreciate your inquiry.
All BMW motorcycles imported by the USA come from the factory with petroleum based Castrol oil (20W50) in the crankcases. BMW Motorrad USA recommends any motorcycle-dedicated oil (synthetic or petroleum base) throughout the life of the engine, with Castrol being the preferred brand. We do not suggest using synthetic oil until after the 6,000 mile service.
Car motor oils have been reformulated and no longer meet the needs of a motorcycle engine. If an automotive oil is used in your motorcycle, clutch damage may be experienced, and BMW Motorrad USA would not be liable for any consequential damage.
If you have any further questions, please respond to this e-mail or contact the Customer Relations and Services Department at 1-800-831-1117. Our office hours are Monday through Friday from 9:00 A.M. to 9:00 P.M., Eastern Standard Time.
BMW Motorrad USA

Tim Vipond sent the following message from the site:Can I switch to synthetic motorcycle oil meeting all the requirements listed in the owners manual at the 600 mile oil change on my 2006 K1200LT? I've heard BMW dealers say never to use synthetic, switch at 18,000 miles or 12,000 miles and heard a rumor that the accessory catalog says a switch can be made at 6,000 miles. I switched to synthetic on my 2000 K1200LT at 6,000 miles and currently have 135,000 miles with no engine problems or even a valve adjustment. AMSOIL says I can switch to AMSOIL synthetic motorcycle oil immediately, but recommend to wait until the 600 mile oil change.Full name: Tim VipondUsername: Email address: [email protected]

I also emailed AMSOIL the same question. They emailed and said I could switch to AMSOIL synthetic motorcycle oil anytime and be covered under their warranty, but suggested I wait until the 600 mile oil change.
So from break in to 600 miles, I rode my bike pretty much normally, but did not lug the engine or live near redline. At 600 miles I put the AMSOIL MCV synthetic motorcycle engine oil in, their SMF122 oil filter and their SVG synthetic gear lube in and now ride it really hard on Sundays like I always did on my 136,600 mile synthetically lubed 2000 K1200LT. Now at 4,000 miles it runs great and has not used a drop of oil that I can tell at the sight glass. I plan on changing the engine oil and filter at 12,000 miles to comply with my AMSOIL warranty and it will comply with the BMW warranty unless BMW can prove the oil did not hold up or was not a motorcycle specific oil via an oil analysis. In which case, AMSOIL pays. So all my bases are covered.
